Gosner stage

System of describing stages of development in anurans

Gosner stage is a generalized system of describing stages of embryonal and larval development in anurans. The Gosner system includes 46 numbered stages, from fertilized embryo to the completion of metamorphosis. It was introduced by Kenneth Gosner in 1960. The system is widely used in herpetology to describe exotrophic tadpoles. Gosner stages are based on certain morphological landmarks that allow comparing development in different species that may greatly differ in age or size.
